I don't like including values in "privilege" because it removes the normative force behind such values. While luck plays a role in success, especially great success, it is well within the reach of many people to get ahead by adopting the right values. Furthermore, adopting these values will make the world a better place and reduce the burden on public services.
I know that non-judgment is the default modern moral stance. But there ought to be a way that we can advertise and support the values of self-reliance and respect for others without sounding accusative. Yes, luck plays a part in success, but why are we so focused on that part and not the easily repeatable values that will help out most poor people who adopt them?
